▎ 摘  要

NOVELTY - Bio-based degradable spunlace cloth polyurethane synthetic leather veneer finished product comprises a base cloth made of a spunlace non-woven fabric blended with viscose and nylon; and obtained by (1) directly coating the coating slurry with biodegradable polyurethane resin on the base cloth, (2) solidifying the bio-based degradable polyurethane resin on the surface of the base cloth, (3) washing the base cloth with clean water, and Dimethylformamide on the base cloth, (4) preheating, ironing, drying and shaping, (5) applying the solvent-based biodegradable polyurethane resin to the release paper, and placing the release paper coated with the biodegradable polyurethane resin into an oven to heat to form a film, and (6) the film is attached to the bottom embryo, and then dried to obtain a finished product. USE - The bio-degradable penetrating water stab cloth polyurethane synthetic leather surface finished product used for shoe manufacturing, furniture manufacturing and luggage manufacturing. ADVANTAGE - The bio-degradable penetrating spunlaced polyurethane synthetic leather surface finished product has excellent biodegradability and biocompatibility, and reduces the pollution to the surrounding environment and protects the health of people.
